CONCRETE PIPE USE MANUALINTRODUCTIONI. INTRODUCTIONConcrete pipe has been used successfully for sewers and culverts in Illinois for over a century. By its verynature, concrete pipe is an ideal drainage product that has the inherent advantage of hydraulic efficiency,structural versatility, local availability, proven durability, construction adaptability, and economic superiority.National specifications have been issued by the American Society for Testing and Materials, AmericanAssociation of State Highway and Transportation Officials, American Society of Civil Engineers and the FederalGovernment for the purpose of ensuring uniform high quality products meeting specific physical requirements.Concrete pipe is the modern manufactured conduit material with the longest history of excellent service andwidest acceptance. New processes, concrete mixes, designs, and unique features are constantly being introducedto make it an even better engineered product for the future.The purpose of this Manual is to provide information on concrete products available, specification designations,and proper application in the sewer and culvert field. Although liability cannot be assumed, the technical datapresented here are considered reliable.1

CONCRETE PIPE USE MANUALSTORM SEWERS & CULVERTSII. STORM SEWERS & CULVERTSINTRODUCTIONStorm sewers carry rainwater, surface water, ground water, cooling water, or other similar flows to a point ofsafe discharge. They help protect much of the land we use for agriculture, industry, transportation, residences,and recreation.Concrete pipe, with its impressive record of strength and durability, is the most economical and reliable choiceof materials available today. Storm sewers require that pipe meet the strength requirements of any depth of filland live load, are hydraulically efficient, are non-combustible, and provide resistance to abrasion.Culverts provide for the free passage of surface drainage water under a highway, railroad, canal, or otherembankment. Proper culvert design prevents the hazards and concurrent expenses of washouts, erosion,flooding, and inundation of adjacent land.Concrete pipe has been used for culverts in Illinois since the 1800s and much of it is still serving reliably.Culverts must be strong to meet the embankment and traffic loads, durable, resistant to abrasion and combustion,and available in a variety of shapes.APPLICABLE SPECIFICATIONS AND RECOMMENDED USECIRCULAR PIPEASTM C14 Concrete Sewer, Storm Drain, and Culvert Pipe (Non-Reinforced)C14 pipe is currently not in general use in Illinois. If desired, it may be used for sizes 12 in. through 36in. diameter with the provision that C76 pipe of comparable strength also be specified. Joints providedfor most storm sewer construction employ cement mortar or mastic compound. For installations withinternal or external head condition, joints may be provided meeting the requirements of ASTM C443utilizing a rubber gasket.ASTM C76 Reinforced Concrete Culvert, Storm Drain, and Sewer PipeC76 pipe is used for sizes 12 in. through 144 in. diameter and is available with bell and spigot or tongueand groove ends utilizing cement mortar or mastic compound joints. These joints are adequate for mostculvert and drainage installations. For the special condition of internal or external heads, joints may beprovided meeting the requirements of ASTM C443 or ASTM C361 utilizing a rubber gasket. ASTMC76 pipe is the most commonly used storm sewer pipe because of its excellent hydraulic capacity,resistance to abrasion and combustion, capabilities in meeting any variety of load conditions, andavailability with a number of related appurtenances.2

CONCRETE PIPE USE MANUALSTORM SEWERS & CULVERTSASTM C655 Reinforced Concrete D-Load Culvert, Storm Drain, and Sewer PipeC655 pipe is used for sizes 12 in. through 144 in. diameter designed for a specific D-load strength.Joints provided for most culvert and drainage employ cement mortar or mastic compound. Theproperties of the pipe are similar to ASTM C76 pipe except that the pipe may be designed for a specificD-load strength and the design accepted on the basis of a statistical analysis of test specimens.SPECIAL SHAPE PIPE AND PRECAST CONCRETE BOXESASTM C506 Reinforced Concrete Arch Culvert, Storm Drain, and Sewer PipeC506 arch pipe is used for sizes 18 in. through 132 in. equivalent circular sizes and is available withtongue and groove cement mortar or mastic compound joint. This arch-shaped pipe is used for minimumcover situations or other conditions where vertical clearance problems are encountered. It offers thehydraulic advantage of greater capacity for the same depth flow than most other structures or equivalentwaterway area. Loads under similar cover conditions are similar to that of circular pipe with the samespan. If arch pipe is not available in a certain area, elliptical pipe may be substituted as an equivalent.ASTM C507 Reinforced Concrete Elliptical Culvert, Storm Drain, and Sewer PipeC507 horizontal elliptical pipe is used for sizes 18 in. through 144 in. equivalent circular sizes withtongue and groove cement mortar or mastic compound joint. The horizontal elliptical pipe is installedwith the major axis horizontal and is used for minimum cover situations or other conditions wherevertical clearance problems are encountered. It offers the hydraulic advantage of greater capacity for thesame depth of flow than most other structures of equivalent waterway area. Loads under similar coverconditions are similar to that of circular pipe with the same span.C507 vertical elliptical pipe is used for sizes 36 in. through 144 in. equivalent circular sizes with tongueand groove cement mortar or mastic compound joint. The vertical elliptical pipe is installed with themajor axis vertical and is used where minimum horizontal clearances are encountered or where unusualstrength characteristics are desired. Hydraulically, it provides higher flushing velocities under minimumflow conditions and carries equal flow at a greater depth than equivalent horizontal elliptical, arch, orcircular pipe. Loads under similar cover conditions are similar to that of circular pipe with the samespan. Special installation techniques are required for vertical elliptical pipe.ASTM C1577 Precast Reinforced Concrete Box Sections for Culverts, Storm Drains, and SewersC1577 box sections are used in sizes of span and rise from 3 ft. by 2 ft. to 12 ft. by 12 ft. Although notspecifically called out by ASTM C1577, 2 ft. by 2 ft. box sections are also locally available. The tablesprovide design requirements for boxes installed under earth, dead and HL-93 live load conditions, fordesign earth cover of 0 to 35 feet. Joints provided utilize tongue and groove type ends with cementmortar or mastic compound joints. Box sections are used where special hydraulic requirements andminimum cover are encountered. They offer the advantage of precast products over cast-in-placeconstruction through low installation costs and minimum inconvenience of weather and traffic delay.3

CONCRETE PIPE USE MANUALSANITARY SEWERSIII. SANITARY SEWERSINTRODUCTIONSanitary sewers are conduits that carry liquid and water-carried wastes from homes, commercial facilities,industrial plants and institutions to a treatment plant for the express purpose of protecting our environment,safeguarding health, and improving our comforts and quality of life.Concrete pipe is the most widely used and accepted permanent product of all sanitary sewer materials. It makesup the greater portion of the sanitary sewer system in most major cities in the United States. Sanitary sewersrequire that pipe meet infiltration limits, meet the strength conditions of any depth of backfill and superimposedload, and provide resistance to the effects of sewage.RECOMMENDED STANDARD SPECIFICATION1.SCOPE1.1 - This specification covers reinforced concrete pipe intended to be used for the conveyance of wastewater.2.REFERENCED DOCUMENTS2.1 ASTM Standards:C76C361C443C655C822C969C11033.Reinforced Concrete Culvert, Storm Drain, and Sewer PipeReinforced Concrete Low-Head Pressure PipeJoints for Circular Concrete Sewer and Culvert Pipe, Using Rubber GasketsReinforced Concrete D-Load Culvert, Storm Drain, and Sewer PipeDefinitions of Concrete Pipe and Related ProductsInfiltration and Exfiltration Acceptance TestingJoint Acceptance Testing of Installed Pre-cast Concrete Pipe Sewer LinesTERMINOLOGY3.1 Definitions - For definitions of terms relating to concrete pipe, see Definitions C822.4.MATERIALS4.1 Reinforced Concrete Pipe – Reinforced concrete pipe shall be manufactured in accordance withASTM C76 or ASTM C655.
